ENCLOSURE 1 NOTICE OF VIOLATION Tennessee Valley Authority Docket Nos. 50-327, 50-328 Sequoyah Units 1 and 2 License Nos. DPR-77, DPR-79 During the Nuclear Regulatory Commission (NRC) special Quality Verification inspection conductea December 12-16, 1988 and January 9-20, 1989, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1988), the violation is listed below:
10 CFR. 50, Appendix B, Criterion XVI, Corrective Action, states that, measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies,- deviations, defective material and equipment, and nonconformances are promptly identified and corrected.
In the case of significant conditions adverse to quali_ty, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition.
The identification of the significant condition adverse to quality, the cause of the condition, and the corrective action taken shall be documented and reported to appropriate levels of management.
Violation 327,328/87-30-01 was issued in March 1988 to address a lack of control over plant evolutions and the status of systems and equipment.
The NRC issued the Notice of Violation to obtain the management attention necessary to resolve the underlying problem.
This previous citation included a system realignment without written or formally-approved instructions; realignment of valves without procedures, or configuration control; and performance of a surveillance instruction without appropriate instrumentation.
The licensee's corrective action for the violation, including strengthening administrative procedures to require procedural adherence and training of plant personnel on the procedures had been completed.
Contrary to the above, the licensee failed te preclude repetition of Violation 327,328/87-30-01 in the radioactive waste area after havir g completed corrective action.
Lack of control over plant evolutions, system status and equipment status was still cvident in the radioactive waste area in that:
1.
multiple evolutiens were performed outside of approved plant I
procedures during spent resin trar sfers from January 11-19, 1989; 2.
known inadequate drawings were utilized affecting procedural
